Abstract: A method is provided to provide fractures in a subterranean formation that utilizes set of first wire line controllable valves (108) to open communication between the inside of a casing (107) and an outside of a casing that has been cemented into a wellbore (101). A wire line controllable valve associated with each of the first valves isolates the inside of the casing downstream of the first valve. The two valves are operated by a wire line actuator. After each successive fracture is formed, the wire line actuator is moved past the next set of valve, changing their positions, and then the next fracture is formed. The valve isolating the downstream portions of the casing are either opened, milled out, or made of degradable material after the operation is complete to enable production from the formation through the fractures into the well bore.

Abstract: A method for underdisplacing fracture proppant in a well bore. The method can include providing a set retainer having a passage configured to receive a wiper plug. The method may also include installing the set retainer in the well bore and injecting a proppant-laden fluid into the well bore, through the passage of the set retainer and through a perforation to create the fracture. The method may include providing a wiper plug configured to be received in the passage of the set retainer. The method may also include inserting the wiper plug into the well bore and allowing the wiper plug to wipe a portion of the proppant-laden fluid past the set retainer and into the fracture. Additionally, the method may include allowing the set retainer to receive the wiper plug.
